336 | * Construct the unshuffled grid. |
337 | * |
338 | * To do this, we simply start at the centre point, repeatedly |
339 | * choose a random possibility out of the available ways to |
340 | * extend a used square into an unused one, and do it. After |
341 | * extending the third line out of a square, we remove the |
342 | * fourth from the possibilities list to avoid any full-cross |
343 | * squares (which would make the game too easy because they |
344 | * only have one orientation). |
345 | * |
346 | * The slightly worrying thing is the avoidance of full-cross |
347 | * squares. Can this cause our unsophisticated construction |
348 | * algorithm to paint itself into a corner, by getting into a |
349 | * situation where there are some unreached squares and the |
350 | * only way to reach any of them is to extend a T-piece into a |
351 | * full cross? |
352 | * |
353 | * Answer: no it can't, and here's a proof. |
354 | * |
355 | * Any contiguous group of such unreachable squares must be |
356 | * surrounded on _all_ sides by T-pieces pointing away from the |
357 | * group. (If not, then there is a square which can be extended |
358 | * into one of the `unreachable' ones, and so it wasn't |
359 | * unreachable after all.) In particular, this implies that |
360 | * each contiguous group of unreachable squares must be |
361 | * rectangular in shape (any deviation from that yields a |
362 | * non-T-piece next to an `unreachable' square). |
363 | * |
364 | * So we have a rectangle of unreachable squares, with T-pieces |
365 | * forming a solid border around the rectangle. The corners of |
366 | * that border must be connected (since every tile connects all |
367 | * the lines arriving in it), and therefore the border must |
368 | * form a closed loop around the rectangle. |
369 | * |
370 | * But this can't have happened in the first place, since we |
371 | * _know_ we've avoided creating closed loops! Hence, no such |
372 | * situation can ever arise, and the naive grid construction |
373 | * algorithm will guaranteeably result in a complete grid |
374 | * containing no unreached squares, no full crosses _and_ no |
375 | * closed loops. [] |
